RE: TF_NEEDSYN flag never set.

Yes, I switched over to using src_current.tar.gz, and that specific bug seems to be gone. Thanx a lot. BUT, the original reason I was looking so closely at this code, still remains a mystery to me. In particular, the comment on lines 2716-2717 of tcp_input.c, along with the following statemen

TF_NEEDSYN flag never set.

I am sorry if this is a dumb question, but I was trying to understand the FreeBSD TCP stack, and In particular I was trying to understand the use of the TF_NEEDSYN flag. This flag is referenced a number of times in tcp_input.c and tcp_output.c, but I don't think that it can ever be set. In par

The point of lists is to be able to benefit from other's experiences so you don't have to waste your time "trying" things that others have already done. I'm not pontificating. I've done the tests. There's no reason for every person who is having to exact same problem to do the same tests over and

Re: High CPU interrupt load on intel I350T4 with igb on 8.3

Try setting your queues to 1, run some tests, then try setting your queues to 2, then to 4... its called tuning, and rather than just pontificating about it, which Barney so loves to do, you can discover what works best. I ran tests last week preparing for a new driver version and found the best re

Re: using netmap

Thank you. I've started using pkt-gen in virtualbox, 2 machines singlwe core-i7 3612QM core, with em cards internal. I see that the sender send about 950 kpps but the receiver is far less (around 200kpps max). Any suggestions why this? Sami On Apr 26, 2013 11:23 AM, "Luigi Rizzo" wrote: > On Fri
